T0 aZZ whom it may concern..-

Be it known that I, CHARLES G. SCHMIDT, a citizen of the United States, and a resident of Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Refrigerators; and I do hereby declare the following to be a clear, full, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame, at-

tion of the cold air, and to improve the structural arrangement of certain parts.

In the following specification and particularly pointed out in the claims at the end thereof is found a full description of my invention, together with its operation, parts, and construction, which latter is also illustrated in the accompanying drawings, in whieh- Figure 1 showsa front View of a refrigerator provided with my improvements, the doors being removed to expose interior and the wall sectioned to show construction. Fig. 2 is a vertical cross-section on line 2 2 of Fig. 1. Figs. 3 and 4 show, at reduced scale, front and rear elevations of the refrigerator. Fig. 5 shows, at enlarged scale, a detail view of a corner section. Fig. 6 shows a portion of the rear side of the refrigerator as shown in Fig. 4.

The inside or inner wall 6 of the refrigerator is constructed of glass, which is applied in sheets of a size covering a whole side, top, or bottom wherever used of the particular compartment inclosed thereby, so that no joints whatever exist, except where such sides, tops, or bottoms join each other, thus avoiding crevices which might afford lodgment for impurities. These sheets are se cured to a sustaining skeleton frame 7, after which against the outside of the latter the outer wall 8 is formed in the usual manner and of the material generally used for such purpose, which is wood. The space between the two may be left empty or be filled with insulating material. are connected to th'eskeleton frame by a waterproof cement, which is also applied These sheets of glass.

along their edges and in which they are embedded thereat. In addition to this the entire back of these sheets is coveredwith a thick coating 9 of such cement, whereby the sheets of glass are strengthened and held together and in position in case they should crack from some cause. The preferable dimensions of these parts are glass three-eighths of an inch thick and cement hack one-eighth of an inch. I furthermore provide screws 11, passing into the :WOOdWOlk through between two sheets where they join in a corner, sufficient of an opening being provided by removing some of the glass at the edges of the sheets. interpose corner-blocks 12, which aid in sustaining the sheets in position and furnish means to form or attach thereto supports'for shelving 13, which is preferably constructed of wire. The plate forming the inner wall at thebottom I prefer to bed upon a layer of,

cement 14. Additional stability is provided 'by cleats 15, placed between the members of the skeleton frame, and to which cleats the sheets of glass are also connected by the ce.

Below the heads of these screws I i off through a waste-pipe 19, ineloscd between the outer and inner wall of the inclosure. Below the ice-chamber are two provisionchainbers 21 and 22, divided by a partition 23. The balance of the space in the upper part of the refrigerator not occupied by the ice-chamber is utilized to receive bottle-racks 24, supported on an open frame 25.

The circulation of air is as indicated by the arrows and proceeds through an opening 26 in the bottom of the ice-chamber, through chamber 21, around the lower edge of partition 23, into chamber 22, and through between the bottle-racks into the ice-chamber, where by coming in contact with the ice it is cooled Rgain. Doors are provided to all the compartments, the one to the bottle-racks and numbered 27 being provided with an independent lock 28, so that this latter com= partment need not be opened when access is wanted to the ice-chamber merely The inner side of the doors to the provision-chambers is preferably also lined with glass.

- A fre dent source of trouble in refrigerators is c rigging up of the waste-pipe 19. To permit easy correction of such disturbance whenever it occurs, I provide such pipe with a removable section 29, to which access is had through a recess 31, formed within the inclosure of the refrigerator. This recess is kept closed by a removable portion 32 of the outer wall, which is snugly fitted in position.

Ilaving described my invention, I claim as (HY-- l. A refrigerator the inelpsure of which con sists of an outer and an inner wall with a space between the two, which forms the insulatingspaee and is occupied by a skeleton frame consisting of uprights and cleats 15, to which these walls connect, and a filling of fibrous material, the outer wall being constructed in the usual manner, while those portions of the inner wall which inclose provision-chambers, are formed of sheets of glass which are as large as the particular surfaces thereby covering all parts of the woodwork inside and are connected to the skeleton frame and to cleats 15 thereof by means of. cement.

2. A refrigerator the inclosure of which consists of an outer and an inner wall with a space between the two, which forms the insulating-space and is occupied by a skeleton frame consisting of uprights and cleats 15, to which these walls connect and a filling of fibrous material the outer wall being constructed in the usual manner, while those portions of the inner wall. which inclose provision-chambers, are formed of sheets of glass covered on their backs with cement and are as large as the particular surfaces thereby covering all parts of the woodwork inside and are connected to the skeleton frame and to cleats 15 thereof by means of said cement,

3. In a refrigerator the combination of an inclosing wall, an ice-chamber, adrip-pan in the bottom thereof,a waste-pipe leading therefrom said pipe passing down through the space between the outer and inner walls, a removable section in said pipe, a recess formed in the inclosing wall and around that portion of the pipe which contains this removable section which recess is open toward the outside and a section of the outer wall removably fitted into this opening.

In tjestimony whereof I hereunto set my hand in presence of two witnesses.
